RIM-LOGKING DEVICE.

Application filed February 23, 1923-. Serial N101. catere T all whom it may concern Be it known: that I, RoDoLrHn PERRAULT, a subject of the King of Great Britain, residing at Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Rim-Locking Devices; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaiins to make and use the same.

The present invention pertains to a novel devicefor looking a tire rim to the felloe of a wheel.

The principalobject of the invention is the provision of a device of this character which may be readily adj usted for the re moval of a rim from the felloe or the application of a rim thereto, and subsequently readjusted for looking: anew rim in position. a

The invention comprises in general a pair of ring sections. upon the circumference of the felloe, and springs which normally tend to press the sections together. The inner ends of the sections overlap and: are formed with racks engageable by a pinion journa-le'd to the felloe. By means of this devicethe sections may be separated: at will against the action of the springs; The rim is formed with lugs which are constructed to lie in recesses formedv in the ring sections when the latter are separated. The rim being. thus'adjusted, the springs are allowed to act to force the sections together, whereby the lugs are engaged by seats formed: in the sections adjacent the recesses. In: this manner the ring is locked against circumferentia'l and lateral shifting.

The invention is fully disclosed in the following description and in the accompanying drawings in which v Figure 1 is a side elevation partly in section of an automobile wheel having the invention applied thereto;

Figure 2 is a perspective view of the felloe and locking ring, the latter being in release position;

Figure 3 isa similar viewwith the looking ring in operative position;

Figure 4 is a section on the line 4-4 of Figure 1;

Figure 5' is a fragmentary perspective view of the inner surface of the rim;

Figure 6 is a sectional view similar to corresponding in number slotted at intervals as at 5 for a purpose pointed out below. I v

Between the side flanges of the felloe and around the clrcuinference thereof are diss posed apair of arcuate members 6- constitutmg a locking ring for the rim. The meeting ends of these membersare reduced and slotted as at 8 to form racks engageable by a pinion 9 journaled: in the body of the felloe. A stem 10 extends inwardly from the pinion through the base of the felloe and has its end squared as at Ilflfor. the accommodation of akeyr The stemis also threaded as at 12 to receive a cap 10;

Each of the ring sections is formed with a plurality of recesses 13- corresponding in number to the slots 5 and adapted to regis-y ter therewith when the sections are" in release position, as shown in: Figure 2; Adj-a.

cent each of the recesses 13', a seat or depression 14k is formed in the member 6 and communicates with the recess. A substantially square member 15' is cut out of the intermediate portion of each arcuaite member and bent inwardly, as shown in: Figure 1. To the; outer surface of the felloe is secu redf fined stop member 16 spaced from the flange 1-5 and: adapted to engage one: end ofv a spring 17, the other end of which bears against the flange; The rim 18 is formed on its inner surface with a pluralityof lugs 19 p tothe sl otsi5 and recesses 13';

In use, the ringsections tend toassume the position shown in Figure 3' because of the pressure of the springs- 17 against the flanges 15. When it is; desired to remove a rim'or apply a new one, the cap 10" is removed and the stem 10 turned to separate the ring sections; For this purposethe key 20 is suitable. The flange' l and one of the sections 6 are formed with apertures 21 and 22 respectively which are adapted to register when the recesses 13 are aligned with i the slots 5. A pin 23 is passed through the in the recesses 13, and from lateral shifting because of the seats 14 being disposedbejneath the lugs.

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing fromthe spirit of t 1e invention as indicated'bythe appended claims.

Having thus fully described the invention, what I claim as new and desire to pro tect by Letters Patent is ,1. A rim locking device comprising in combination with a flanged'felloe having slots formed in the flange, a pair of arcuate ring sections disposed upon the circumference of the felloe and provided with recesses adapted to register with said'slots, said sections having depressed seats formed therein ad acent said recesses, stop members fixed to said felloe, springs bearing against said stop members and sections and adapted to force the latter together, andfmeans for forcing I said sections apart.

- 2. A rim locking device comprising in combination with a flanged felloe having slots formed in the flange, a pair of arcuate ring sections disposed upon the circumference of the felloe and provided with recesses adapted to register with said slots, said sec: tions having depressed seats formed therein adjacent said recesses, stop members fixed to said felloe,s}: rings bearing against said stop members and sections and adaptedto force the latter together, and meansior forcing said sections apart, the felloe flange and one of said sections being provided with apertures adapted to register when the recess is in-registration with the slot.

3. A rim locking device comprising in combination with a flanged, relloe having slots formed in the flange, a pair of arcuate ring sections disposed upon the circumference of the felloe and provided with recesses adapted to register with said slots, said sections having depressed seats formed therein adjacent said recesses, stop members fixed to said felloe,springsbearing against said stop members andsections and adapted to force thelatter together, means for-forcing said sect-ions apart, and a rim having lugs on its inner surface adapted to pass through said slots and into the recesses, said lugs being engageable by said seats.

4. In combination with a felloe having a flange and slots formed therein, a rim loclo ing device comprising a pair of ring sections disposed upon the circumference of the 'felloe, the meeting ends of said sections overlapping and being formed with racks, a

rotatable pinion journaled to the felloe and engaging said racks, said sections being formed with recesses adapted to register with the slots when the sections are separated, seats formed in said sections adjacent the recesses, fixed stop members secured to the felloe, flanges bent inwardly fromsaid sections andspaced from the stop members, springs'bearing against said stop'members and'flanges and adapted to force said sections together.

5. In combination with a felloe having a flange and slots formed therein, a rim looking device comprising apairof rin'gl sections disposed upon the circumference ofthe felloe, the meeting-ends of said sections overlapping and being formed with racks, a rotatable pinion journaledto the felloe and engaging said racks, said sections being formed with recesses adapted to register with the slots when the sections are sepa rated, said felloe flange and one of the ring sections being formed with aperture adapt-' ed 'to register when the recesses are in .registration with the slots, seats formed in said sections adjacent the recesses, fixed stop members secured to the felloe, flanges bent inwardly fromsaid sections and spaced from the stop members, springs bearing against said stop'members and flangesand adapted to force said sections together.
